那个啥 图片照错了 题目里面没有说要用 “%f” 求给个不用"%f"的码。
"Your code will be provided an unknown value for x. (That is, don't specify x yourself.)
Write an if/elif/else statement which implements this piecewise expression and prints the result in the format 'x N'. Assume that the provided value is called x."
我写的代码如下:
if x < -1:
x_N = 0
print (x_N)
elif x>= -1 & x<=0 :
x_N = 1+x
print (x_N)
elif x>= 0 & x<=1 :
x_N = 1-x
print (x_N)
else:
x_N = 0
print (x_N)
elif x>= -1 & x<=0 :
这里用 and 而不是 &
别的地方类似
x使用前必须声明,是在哪声明的?
你的x没有定义,在使用前要先对x赋值
使用格式的代码如下,保留6位小数
# x = -0.250000
if x < -1:
x_N = 0
elif -1 <= x <= 0:
x_N = 1 + x
elif 0 <= x <= 1:
x_N = 1 - x
else:
x_N = 0
str1 = "%.6f %.6f" % (x, x_N)
print(str1)
没有格式话代码如下
# x = -0.250000
if x < -1:
x_N = 0
elif -1 <= x <= 0:
x_N = 1 + x
elif 0 <= x <= 1:
x_N = 1 - x
else:
x_N = 0
str1 = "{0} {1}".format(x, x_N)
print(str1)
楼主按需使用吧
